Why do we study the shapes and activities of volcanoes?

Type response here

LET'S TRY...

Fill in the Blanks

The simplest type of volcano. They are built from particles and lava ejected from a single vent.

Type answer...

Multiple Choice

The diagram shows a model of the movement of two tectonic plates. When the plates collide, on plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce-

fossil layers

volcanic islands

deep-sea sediment

seafloor spreading

Multiple Choice

This common type of volcano is made up of alternating layers of ash and lava.

Shield volcano

Composite / Stratovolcano

Cinder cone

Fissure volcano

Multiple Choice

Describe the role of tectonic plate boundaries in the formation of the Ring of Fire.

They create stable regions with no volcanic activity.

They are areas where plates move apart, causing earthquakes.

They are zones where plates collide or slide past each other, leading to volcanic activity.

They are regions where plates are stationary, preventing volcanic eruptions.

Multiple Choice

What is the function of the crater in a volcano?

It stores magma

It is a bowl-shaped depression

It is the main vent for lava

It is a type of rock formation

Multiple Choice

What is the function of the conduit in a volcano?

To allow magma to escape

To provide a pathway for magma

To create fissures

To cool down lava

Multiple Choice

What is the function of the vent in a volcano?

To release volcanic materials

To support the volcano structure

To cool down lava

To create ash clouds

Fill in the Blanks

Typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.

What are the characteristics of a stratovolcano?

Multiple Choice

What are the characteristics of a shield volcano?

Formed by explosive eruptions

Resembles a warrior's shield

High and steep

Erupts violently

Multiple Choice

What is a cinder cone and how is it formed?

A type of volcano formed by lava flows

Multiple Choice

What are the three classifications of volcanoes shown in the image?

Potentially Active Volcanoes

Inactive Volcanoes

Dormant Volcanoes

Multiple Choice

What are the characteristics of active volcanoes?

Exhibited volcanic activity

No historical eruptions

Located only in specific regions

Always erupting

Multiple Choice

What are the characteristics of potentially active volcanoes?

They are old and inactive

They are young-looking and suspected to generate seismic activities

They are always erupting

They are located only in one region

Multiple Choice

What are the characteristics of inactive volcanoes?

They have historical records of eruptions

They are severely weathered and eroded

They are currently erupting

They are located only in the Philippines

Reorder

Reorder the following to describe what could happen after a volcanic eruption.

Hint - Start with the volcanic eruption!

A volcano erupts on the surface of the Earth.

Lava cools on the side of a volcano to form extrusive igneous rock.

Rain slowly weathers and erodes the volcanic rock.

Particles of volcanic rock known as sediment are deposited at the bottom of a nearby lake.

More layers of sediment are added and the layers below are slowly compacted and cemented to form a sedimentary rock.

Multiple Choice

The image below shows lava flowing from the Krafla volcano in Iceland. How is a new land feature formed from lava?

by the constructive process of lava hardening to add new land on top of the ground

by the constructive process of lava depositing sediment to build up the surface of the ground

by the destructive process of lava flow carrying sediment away from the volcano by erosion

by the destructive process of lava weathering rock to carve a new landform in the volcano

Open Ended

Why should you keep yourself informed about volcanic activities?

Type response here

Multiple Choice

What are the main differences between effusive and explosive volcanic eruptions?

Effusive eruptions are less violent than explosive eruptions.

Explosive eruptions produce more lava than effusive eruptions.

Effusive eruptions occur when there is a high amount of dissolved gases.

Explosive eruptions are characterized by a gentle flow of lava.
